AMD's next-gen RDNA 5 GPU leak: Radeon RX 10900 XT has 36GB GDDR7, TSMC 3nm, RTX 6090 killer

AMD's next-gen RDNA 5-based flagship Radeon RX 10900 XT graphics card will reportedly sport a huge 154 CUs, 36GB of GDDR7 memory with 1.7TB/sec memory bandwidth, and will have performance that will rival NVIDIA's next-gen GeForce RTX 6090 graphics card.

In his latest video, Tom from Moore's Law is Dead reports on his latest leaks that would see the Radeon RX 10900 XT (or whatever it is called, but the RX 10900 XT sounds fantastic). We are looking at the "AT0" die that will feature a huge 154 Compute Units of RDNA 5 GPU power, 40MB of L2 cache, a 380W TDP, and 36GB of GDDR7 memory clocked at 36Gbps on a 384-bit memory bus that would pump out 1.728TB/sec of memory bandwidth.

This would result in AMD's next-gen Radeon RX 10900 XT graphics card competing with NVIDIA's next-gen GeForce RTX 6090, meaning the company is aiming for its new RDNA 5 flagship GPU to be faster than the current RTX 5090, which is something all gamers want to hear. These are just estimates in performance so things can change obviously.

The 380W TDP will be the downfall of the Radeon RX 10900 XT if the leaks are true, as that is a LOT of GPU horsepower to battle the RTX 6090 with just 380W, considering the RTX 5090 has a 600W TDP. Again, these are leaks and things can change, as there is a lot of time between now and when RDNA 5 appears in 2026-2027.

AMD's possible RDNA 5-based Radeon RX 10000 series GPU offerings:

• Radeon RX 10900 XT: 154 CUs, 36GB GDDR7 on 384-bit bus aimed at RTX 6090
• Radeon RX 10700 XT: 64 CUs, 18GB GDDR7 on 192-bit aimed at RTX 5080 - RTX 4090
• Radeon RX 10070 GRE: 48 CUs, 16GB GDDR7 on 160-bit aimed at RX 9070 - RTX 4080 SUPER
• Radeon RX 10060 XT: 44 CUs, 12GB GDDR7 on 128-bit bus aimed at RTX 5060 Ti - RTX 5070
